BOTTLE.

SPEGIFICATION forming part of Letters Patent No. 593,999, dated November 23, 1897'.

Application filed October 21 1896.

To all whom 't may concern:

Be it known that I, SIMON F. FRASER, a citizen of the United States, residing at West Albany, in the county of Albany, State of New York, have invented certain new and useful Improvements in Bottles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same. i

My invention relates to bottles in general, but more particularly to the construction of the neck thereof and to such a combination of elements as will prevent refilling of the bottle when once emptied.

In the drawing forming a portion of this specification I have shown a longitudinal section of a bottle constructed in accordance with my invention.

Referring now to the drawing, a bottle is for-med comprising a body portion a of any desired shape, having a neck b, the upper portion of the bore of which' is cylindrical in form, while the lower portion of the bore is frusto-conical, the major diameter thereof being greater than the diameter of the cylindrical bore. The major portion of the lastnaned bore is directly adjacent the cylindrical bore, resulting in an annular shoulder c. The lower portion of the frusto-conical bore forms a valve-seat for a similarly-shaped valve d, the upper surface of which latter is formed with a centrally-arranged coni'cal projection e, at the base of which is an annular recess f, surrounded by awall g, for purposes as will be hereinafter explained.

In order to prevent tampering with the valve d, I provide a guard-plate h,-wlich latter consists of a cup-shaped metal piece having a rentrant base 'L', said rentrant portion being provided with perforations k, which latter .are so formed as to guide a wire or other Serial No. 609 ,541. (No model.)

then pressed downwardly until its periphery passes beneath the shoulder c, when its elasticity will cause it to eXpand, after which it will be held immovably in'place.

It will be readily understood that the particular shape of the top of the valve may be varied as desired without departing from the spirit of my invention, it being necessary only that there shall be a central projection in alinement with the perforations in the guard-plate and that there be an annular Wall inclosing a recess about the projection.

Having thus described my invention, what I claim is- The combination with a vessel having a tubular neck provided with an annular shoulder forming a valve-seat of a valve adapted to enter said seat, said valve having a central, curvilinear upward projection surrounded by an annular groove, the lateral curve of said groove being a continuation of SIMON F.
